Image upload corruption with SeaweedFS S3 API
Problem Description I'm experiencing an issue where images uploaded through Django (using boto3) to SeaweedFS's S3 API are corrupted, while uploads through S3 Browser desktop app work correctly. The uploaded files are 55 bytes larger than the original and contain a Content-Encoding: aws-chunked header, making the images unopenable. Environment Setup Storage: SeaweedFS with S3 API Proxy: nginx (handling SSL) Framework: Django Storage Client: boto3 Upload Method: Using Django's storage backend with PrivateStorage Issue Details When uploading through S3 Browser desktop app: File size matches original Image opens correctly No corruption issues When uploading through Django/boto3: File size increases by 55 bytes Response includes Content-Encoding: aws-chunked Image becomes corrupted and unopenable First bytes contain unexpected data (100000) Last bytes end with .x-amz-checksum- Example of Corrupted File Original file size: 12345 bytes Uploaded file size: 12400 bytes (+55 bytes) First bytes: 100000...

Is there a way to disable the aws-chunked encoding in boto3? Are there specific headers … -
How to avoid redundant manual assignment of environment variables in Django settings?
In my Django project, I store configuration variables in a .env file for security and flexibility. However, every time I introduce a new environment variable, I have to define it in two places: .env and settings.py. As the project grows and the number of environment variables increases, settings.py gets cluttered with redundant redefinitions of what’s already in .env. Is there a way to automatically load all .env variables into Django’s settings without manually reassigning each one? Ideally, I want any new variable added to .env to be instantly available from settings module without extra code. What I can think of is something like: from dotenv import dotenv_values env_variables = dotenv_values(".envs") globals().update(env_variables) Or even something a little bit better to handle values of type list. for key, value in env_variables.items(): globals()[key] = value.split(",") if "," in value else value # Ensure ALLOWED_HOSTS is always a list ALLOWED_HOSTS = ALLOWED_HOSTS if isinstance(ALLOWED_HOSTS, list) else [ALLOWED_HOSTS] But I do not like to mess around with globals(). -
Django app performance issues with cloud PostgreSQL & Redis
I recently deployed my Django app on Railway, where I set up PostgreSQL and Redis and connected them to my project. However, I’ve noticed a drastic slowdown in query and cache performance compared to running locally—by several orders of magnitude. For example, one of my views executes queries in 2.58ms on my local database but takes 7411.42ms on Railway. Similarly, the same view’s cache time is 24.14ms on local Redis but 2122.14ms on Railway. I expected some performance drop when moving to a cloud-hosted setup, but this level of slowdown seems excessive. Initially, I suspected an incorrect connection setup on Railway, but after testing with Redis Cloud, the performance remained similar to Railway’s Redis. I haven’t tested another cloud database yet. Does anyone have insights into what might be causing such a drastic difference? Here’s my database setup in settings.py: DATABASES = { 'default': dj_database_url.config(default=os.getenv('DATABASE_URL')) } and cache setup: SESSION_ENGINE = "django.contrib.sessions.backends.cache" SESSION_CACHE_ALIAS = "default" SELECT2_CACHE_BACKEND = "select2" CACHES = { "default": { "BACKEND": "django_redis.cache.RedisCache", "LOCATION": REDIS_URL, "OPTIONS": { "CLIENT_CLASS": "django_redis.client.DefaultClient", } }, 'select2': { "BACKEND": "django_redis.cache.RedisCache", "LOCATION": REDIS_URL, "OPTIONS": { "CLIENT_CLASS": "django_redis.client.DefaultClient", } } } Any help would be greatly appreciated! Thanks! -

How to properly connect PostgreSQL with Django?
I'm working on a Django project and using PostgreSQL as my database.

I also verified that my credentials are correct. What could be the issue? -
Django ManyToMany Relationship Not Returning First Available Size in View
I am working on a Django e-commerce project where a product can have multiple sizes. However, I am facing an issue where, if no size is explicitly selected by the user, the system should automatically take the first available size of the product. Currently, it always returns "No Size", even though sizes exist for the product.

Trouble setting PORT in Django/Heroku Procfile using Waitress
I'm trying to deploy my Django application with Heroku (on Windows), and using Waitress (because Gunicorn no longer runs on Windows??). When I hard coded the PORT number, I was able to run it fine. When I try to define PORT in the Procfile as an environment variable Procfile: web: waitress-serve --port=$PORT [projectname].wsgi:application .env WEB_CONCURRENCY=2 PORT=$PORT settings.py import environ from environ import Env ... PORT = env('PORT') running "heroku local" produces ValueError: invalid literal for int() with base 10: '$PORT' I keep seeing mention that "$PORT" is not appropriate for Windows. However I can't figure out what I'm missing. I've seen suggestions that "%PORT%" would work for Windows, but I haven't had success. If there is a Windows friendly syntax, would I need to use it in both .env and Procfile? -

Django app works locally but shows "Unhandled Exception" on PythonAnywhere (Logs available)
Link to the youtube video: https://youtu.be/iJrUiem10iI I have developed a Django application that includes features like downloading YouTube videos (using yt-dlp) and potentially converting file formats. The Problem: The application runs perfectly fine on my local machine using python manage.py runserver. I can access the views, for example at http://127.0.0.1:8000/converter/, and the functionality works as expected. However, after deploying the application to PythonAnywhere (using the free tier), I encounter an error. When I try to access my site at https://kristjan.pythonanywhere.com/ or the specific app URL https://kristjan.pythonanywhere.com/converter/, I get a generic PythonAnywhere error page stating: Something went wrong :-( Something went wrong while trying to load this website; please try again later. Error code: Unhandled Exception Self-note: The error page provides links to logs, which should contain the specific traceback. What I've Done and Checked: Local Server: Confirmed the app works correctly locally via runserver. The URL http://127.0.0.1:8000/converter/ loads the correct index.html template. Virtual Environment: Created a virtualenv on PythonAnywhere at /home/Kristjan/.virtualenvs/djangoappvirtualenv. I activated this virtualenv and installed all necessary packages (Django, yt-dlp, etc., matching my local environment as closely as possible) using pip install -r requirements.txt (or individually) within a PythonAnywhere console.

password reset email in django

Why do filters affect the result of StringAgg?
I'm using StringAgg and order as follows: # Get order column & annotate with list of credits if request.POST.get('order[0][name]'): order = request.POST['order[0][name]'] if order == 'credits_primary': releases = releases.annotate(credits_primary=StringAgg( 'credits__entity__name', delimiter=', ', filter=Q(credits__type='primary'), ordering='credits__id' )) elif order == 'credits_secondary': releases = releases.annotate(credits_secondary=StringAgg( 'credits__entity__name', delimiter=', ', filter=Q(credits__type='secondary'), ordering='credits__id' )) else: order = 'title' # Order releases if request.POST.get('order[0][dir]') == 'desc': releases = releases.order_by(F(order).desc(nulls_last=True), 'title') else: releases = releases.order_by(F(order).asc(nulls_last=True), 'title') for release in releases: try: print(release.credits_primary) except: pass try: print(release.credits_secondary) except: pass This in itself works exactly as expected: the ordering is what I expect, and print returns the values I expect. However, when I apply filters before this, it starts behaving strangely. Namely, sometimes it's fine and still works as expected, sometimes each credits__entity__name is repeated a random number of times, sometimes the annotation just returns None even though there are values. I can't figure out a pattern here. Below are the filters I'm applying, note that exclude as far as I can tell does not cause this problem: if request.POST.get('entity'): releases = Release.objects.filter(credits__entity=request.POST['entity']) else: releases = Release.objects.all() records_total = releases.count() # Filter by type if request.POST.get('type'): query = Q() for type in loads(request.POST['type']): if type in Release.TYPES_P_TO_S: query.add(Q(type=Release.TYPES_P_TO_S[type]), Q.OR) releases … -
Why is the data-tags attribute not preserved in my Django form widget? autoComplete DAL Select2
I'm using a CharField with a custom widget (ListSelect2) from the django-autocomplete-light library. I have a set of data-* attributes, including data-tags, that I want to be passed to the HTML output, but it doesn't seem like the data-tags attribute is being preserved or rendered correctly in the final after form is saved. industry_type = forms.CharField( widget=autocomplete.ListSelect2( url='/career-listings/industry-autocomplete/', attrs={ 'class': 'w-full px-4 py-2 border border-gray-300 rounded-lg shadow-sm focus:outline-none focus:ring-2 focus:ring-blue-500 focus:border-blue-500 transition duration-200', 'data-placeholder': 'Industry', 'data-minimum-input-length': 1, 'data-theme': 'tailwindcss-3', 'data-tags': 'true', # The attribute I'm trying to preserve 'id': 'id_industry_type', }, forward=['name'], ), required=True, ) What happens instead: The data-tags attribute does not appear in the HTML after form is saved. The field Things I've tried: I added data-tags to the attrs dictionary of the widget. I ensured that the widget is being properly rendered in the template. The data only data-tags is not preserved on form is submitted. -
Getting list of distinct ManyToManyField objects
Given these models: class Format(models.Model): name = models.CharField(unique=True) # More fields... class Release(models.Model): formats = models.ManyToManyField(Format, blank=True) # More fields... When I have a queryset of Releases (e.g. through releases = Release.objects.filter(foo='bar')), how do I get a list of the formats in that queryset, as objects and distinct? Neither of the following achieve this: # produces a list of dicts with IDs, not distinct e.g. [ { 'formats': 1 }, { 'formats': 2 }, { 'formats': 1 } ]: formats = releases.values('formats') # produces a list of IDs, not distinct, e.g. [ 1, 2, 1 ]: formats = releases.aggregate(arr=ArrayAgg('platforms'))['arr'] The only way I can think of is manually creating a list by looping through the IDs, checking if it already exists in the list, and if not adding it with formats.append(Format.objects.get(id=the_id)), but I would really like to avoid doing that, if possible. -

Django Search Query Vulnerable to XSS - How to Prevent It?
